Description of Driving Event:
Orbiter Avionics Modifications
Lesson(s) Learned:
The Multi-Function Electronic Display System (MEDS) in the orbiter is being implemented with display functions and formats that mimic the present electromechanical and cathode ray tube presentations. There are significant potential safety and operational benefits from enhancing the amount, type, and format of information shown on the MEDS displays.
Recommendation(s):
The Space Shuttle program should commit to a significantly enhanced MEDS display as soon as possible. The MEDS advanced display working group or a similar multidisciplinary team should be tasked with identifying specific modifications and an associated timetable so that the opportunities inherent in MEDS can be realized.
Evidence of Recurrence Control Effectiveness:
The SSP has established an enhanced MEDS program that includes hardware and software enhancements to take full advantage of MEDS capabilities. This includes hardware expansion as well as utilization of inherent MEDS capabilities to provide better displays and improve crew situational awareness. Additionally, an SSP Cockpit Upgrade Team is being formed to develop advanced display and application concepts for future implementation into MEDS/enhanced MEDS/future avionics upgrades capability. The Cockpit Upgrade Team will also participate in avionics upgrades discussions in order to anticipate future hardware and software changes and develop advanced cockpit applications to further improve crew awareness and reduce crew training requirements. Initial testing of new applications for enhanced MEDS will begin in June 1997.
